Driving path test module includes image collecting device and data processing equipment, wherein, the installation of described image harvester In the front of the car, described image harvester is used to gather vehicle front-end image signal in the process of moving, and will Described image signal transmission to the data processing equipment, the data processing equipment carries out described image signal on denoising, wheel Wide extraction process, and the picture signal after processing is transmitted to the control device, institute is judged by the picture signal after processing State vehicle whether straight-line travelling, if straight-line travelling, then the control device indicates that the trigger circuit produces low level triggering Signal, and the low level trigger signal is transmitted to the steering indicating light call-back device, the steering indicating light call-back device is by described in Vehicle left steering lamp and right turn lamp extinguish, if not straight-line travelling, then the trigger circuit does not produce trigger signal.

Turn signal according to an embodiment of the invention adjusts back system, wherein, described image harvester includes Ccd image gathers sensor and video capture card.

Turn signal according to an embodiment of the invention adjusts back system, wherein, the installation of described image harvester In on the front of the car central axes.

Turn signal according to an embodiment of the invention adjusts back system, wherein, the collection of described image harvester Road void/real diagram picture, the data processing equipment comes out the contours extract of the road void/real diagram picture, by the road The profile information of road void/real diagram picture is transmitted to the control device, if if the contour line of road void/real diagram picture and institute It is vertical to state front of the car, then the control device judges its straight line traveling, if the profile of road void/real diagram picture If line and the front of the car out of plumb, the control device judge the vehicle not with straight-line travelling.

Turn signal according to an embodiment of the invention adjusts back system, wherein, the data processing equipment is right When the image of described image harvester collection carries out the contour extraction processing, the energy of image is calculated first, wherein,For custom parameter, value range 0-1,For in image outline Portion's average gray value,For average gray value outside image outline,For averaged curve function,, whereinFor custom parameter;Then the maximum of image energy is asked for, is calculated with thisValue, maximum image zooming-out profile is finally reached to energy.

Brief description of the drawings

A kind of turn signal that Fig. 1 is the present invention adjusts back system schematic.

Embodiment

Turn signal of the present invention readjustment system is described in detail with reference to the accompanying drawings and examples.

As shown in Figure 1, the present invention provides a kind of turn signal readjustment system, car is automatically closed during straight-line travelling Steering indicating light, therefore, the present invention utilize driving path test module, steering indicating light call-back device, control device and trigger circuit, During its straight line traveling, vehicle turn signal is automatically closed.

Turn signal readjustment system includes:Driving path test module, steering indicating light call-back device, control device and triggering Circuit;

Driving path test module includes image collecting device and data processing equipment, wherein, image collecting device is installed on car Front end, image collecting device are used for collection vehicle front-end image signal, and picture signal is transmitted to number in the process of moving According to processing unit, data processing equipment carries out picture signal denoising, contour extraction processing, and the picture signal after processing is passed Transport to control device, by the picture signal after processing judge vehicle whether straight-line travelling, if straight-line travelling, then control device Indicate that trigger circuit produces low level trigger signal, and the low level trigger signal is transmitted to the steering indicating light readjustment dress Put, steering indicating light call-back device extinguishes vehicle left steering lamp and right turn lamp, if not straight-line travelling, then trigger circuit does not produce Trigger signal;

Image collecting device includes ccd image collection sensor and video capture card.

Image collecting device is installed on front of the car central axes.

Vehicle on road when driving, if straight-line travelling, then road void/real diagram of image acquisition device as Contour line is vertical with front of the car, if not straight-line travelling, then road void/solid line image contour line of image acquisition device With front of the car out of plumb, by road void/real diagram picture come judge vehicle whether the applicable various road conditions of straight-line travelling, and sentence Disconnected result is more accurate, when definite vehicle is straight-line travelling, can close the steering indicating light of unlatching.
